Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional detection methods (HPLC, GC, MS) are used, then measurement precision is improved, but detection time increases and device complexity increases
Solution Approach 1:
The patent introduces an artificial antigen as an intermediary substance that enables indirect detection of fentanyl through antibody-antigen binding. This mediator allows the use of simpler, faster immunoassay methods while maintaining detection accuracy, resolving the contradiction between measurement precision and detection time
Solution Approach 2:
The patent replaces complex mechanical/instrumental detection systems (HPLC, GC, MS) with a biochemical detection system based on antibody-antigen binding. This substitution enables rapid detection without requiring expensive instruments or professional technicians, while maintaining measurement precision through specific immunological reactions
2Measurement precision
If traditional detection methods (HPLC, GC, MS) are used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical/instrumental detection systems with a biochemical detection system based on antibody-antigen binding. This substitution eliminates the need for expensive HPLC, GC, or MS instruments, reducing device complexity while maintaining measurement precision through specific immunological reactions
Solution Approach 2:
The artificial antigen serves as a biochemical intermediary that enables detection through simple antibody binding reactions. This approach replaces the need for complex instrumental systems with a straightforward immunological assay, reducing device complexity while preserving measurement accuracy
3Measurement precision
If traditional detection methods are used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces operationally complex instrumental methods with a simple biochemical assay based on antibody-antigen binding. This substitution eliminates the need for professional technicians to operate complex instruments, making the detection method easy to perform while maintaining measurement precision through specific immunological reactions
Solution Approach 2:
The artificial antigen enables a simple operational procedure based on antibody binding, replacing the need for complex instrumental operations. This intermediary allows non-experts to perform accurate detection through straightforward immunological reactions, improving ease of operation while maintaining measurement precision
4Ease of manufacture
If small molecular compounds are used directly, then manufacturing simplicity is improved, but reliability deteriorates
Solution Approach 1:
The patent creates a composite structure by conjugating the small molecular hapten with a macromolecular carrier (BSA). This composite artificial antigen combines the simplicity of small molecule synthesis with the immunogenicity of large molecules, resolving the contradiction between manufacturing ease and immunological reliability
Solution Approach 2:
The patent divides the artificial antigen into two functional segments: a hapten portion that provides structural similarity to fentanyl for antibody recognition, and a carrier protein portion that provides immunogenicity. This segmentation allows the small molecular compound to be manufactured simply while the carrier ensures reliable antibody generation
